Signaling and selection for layers in scalable video

A method for decoding a transport stream carrying high efficiency video coding (HEVC) video streams that include one or more temporal layers and one or more spatial layers, each layer encoded in a respective elementary stream, the transport stream signaling individual layer parameters for layers in the HEVC video streams, the method comprising:

• identifying in the transport stream an HEVC video descriptor including one or more syntax elements that apply to a whole HEVC layered stream;
• determining from the HEVC video descriptor one or more elements that indicate whether a plurality of temporal layers are present in one or more spatial layers in the HEVC layered stream;
• identifying in the transport stream an operation point descriptor including one or more syntax elements that:
• signal individual layer parameters for each temporal layer present in the HEVC layered video stream, and
• identify an operation point including one or more temporal layers and one or more spatial layers present in the HEVC layered stream;
• wherein the individual layer parameters signaled in the operation point descriptor are associated to a relevant elementary stream using a Program Map Table (PMT);
• and
• buffering for a decoding process each temporal and/or spatial layer in the HEVC layered stream using parameters signaled in the operation point descriptor, wherein each temporal and/or spatial layer in the HEVC layered stream is individually buffered.
